Nitrogen superfine air classifier for powder is a kind of advanced dry grading equipment which specializes in superfine powder multistage superfine separating. With innovated self-shunting grading technology and centrifugation technique, the air classifier system is working in full sealed condition under the nitrogen protection. With nitrogen recycling, it features low cost and no pollution. The industrial equipment is ideally used for grade work of different readily oxidizable substances. The whole set of classifying equipment is featured by high grading efficiency, high grading precision, concentration particle size, convenient use, safety and reliability. The controlling system is equipped with PLC programmable controller, and the programmed control on system function is available, realizing automatic feeding, automatic discharging, system detecting, malfunction alerting and automatic protection. Additionally, the air classifier is equipped with touch screen man-machine interface display, providing good control platform to set and change system running parameters.
Nitrogen superfine air classifier for powder is mainly consisted of automatic feeding system, grader I, grader II, grader III, cyclone collector, duster, induced draft fan, cooler, secondary air circulation system, rack, electrical automatic operation controlling system, and safety system for anti-explosion (Conform to the standard of state explosion proof standard). The parts of the whole set of classifying equipment that contacts with the materials are completely made of stainless steel 304.
